I have recently been working on the tip design on my tucking forks to reduce the pinpoint loading issues that causes the small dimple damage at the end of the tuck.
This is the main issue I see with using the tucking forks as this damage must normally be sanded away to completely remove it.
This "latest design" increases the diameter at the point which reduces the loading effect. From my testing this is a good balance between the overall quality of the tuck shape and the pinpoint loading damage.
